:ELECTBIG WATER-LEVEL INDICATGR.

To all whom it may concern:

Be it known that I, Enwaiin E. Fineness, a citizen of the United States, residing at Eastport, in the county of Anne Arundel and State of Maryland, have invented certain new and useful Improvements in Electric WatenLevel Indicators, of which the following is a specification.

This invention relates to an improved electric water level indicator and has particular reference to an improved device for indicating the level of water in tanks.

The object of the invention is to provide a tank with an improved construction of Water level indicator so that the approximate depth of water may be determined at a point re-- mote from the tank and a signal may be sounded as the various levels of Water in the tank are reached. V

The invention consists in the novel construction, combination and arrangement of devices hereinafter set forth in. the claims, and the accompanying drawing illustrates its application.

Figure l, of the drawing shows an exterior elevation of a tank embodying the features of the invention and also shows the indicator and alarm devices and a diagram matic arrangement of electrical connection between them. Fig. 2 shows a vertical sectional detail through thewall oi the tank and also showsthe terminals and the float for closing the circuit through the latter. Fig. 3, is a top plan view of a portion oithe tank directly over the terminals and float, and Fig. 4:, is an enlarged sectional detail showing the manner of securing the terminals in the tank wall.

Referring to the drawing the numeral, 1, designates a tank which may be constructed of wood, metal, concrete or any suitable material but which is shown as formed of wood, and in .the presentinstance has a plurality of encircling hoops, 2, whose ends are held by suitable devices, 3, that are well-known to the trade and therefore not shown in detail. The tank is provided with a plurality of stems that extend through the wall thereof from the outer t0 the inner side and said stems are arranged in spaced-apart pairs with one pair above another. In the form shown the tank has five pairs of stems desig- Spccification of Letters Eatent.

specti.vely,the pair of stems, 4, being the.

each pair of stems may form terminals of an electric circuit as will presently be more fully described.

By referring to 4, it will be seen that each stem or terminal has an enlarged outer end, 9; a collar, 10, and a'reduced inner end, 11, which is circular in cross-section. Suit able insulating material, 12, is provided between the stem and the tank so as to insulate the stems from each other and also from the wall in case the latter is of a materialthat is a conductor of electrical current. A binding post, 13, screws into. the outer enlarged end, 9, of the stem or terminal and an adjustable: contact head, 1%, is screwed into the reduced inner end, 11, of said stem. By preference the adjustable contact heads, 1 are beveled around their edges for a purpose presently to be explained.

By referring to Figs. 2 and 3 it Will be seen that a guide bar, 15, which is squarein cross-section extends vertically in the tank in a vertical plane between the spaced-apart pairs of stems or terminals,-the lower end of the bar having a lateral extension, 16, that rests upon and is secured to the bottom, 17, of the tank, and the upper end having a horizontal extension, 18, with lateral flanges, 19, that are secured to the tank wall above the stems or terminals. The guide bar, 15, is thus held rigidlyin the tank and ex tends from a point above the highest pair of stems or terminals, 8, to apoint below the lowest pair of stems or terminals, 4. A float, 20, is sustainedon the guide bar, 1-5, and in the present instance this float has a passage extending therethrough from the upper to the lower side that conforms to the cross-sectional shape and permits the'passage of the bar, 15, so that said float may move vertically on the bar and rise and fall with the water in the tank. The float has a contact wall, 21, that is preferably formed of metal, but obviously any electrical conductor on the float that will simultaneously brush over the contactheads, 141, of the stems or terminal's' may be employed.

In carrying out the invention I make use each pair ia M annuncicior i'ncc'iianism,

.i am aware of the fact that Water is supposed to be a. conductor of electricity and While this may be true in many instances I have found by actual practicc of the apparatus herein. shown that water clocs iiot iii this case conduct the current from cnc set of terminals to another or from one terminal of a pail to thc other terminal of the same pair of terminals and that with the appw lotus shown the operation is precisely as doscribcd and that the annunciatcr and signal devices are not operated until the float forms the contacts between the terminals.
